Thank you so much for your effort. The mirror has not sync yet.
But I have solved the problem.
I was looking for some sort of log of s6 without success but then I look at the dbus log and noted a lot of lines like this:

where 'libmozjs' are mentioned.
So I did a little research and findout that is part of some javascript project named spidermonkey that leads me to the 'libproxy-mozjs' package.
I installed the libproxy-mozjs and everything is back to normal.
Strange thing, I have never had this package before, so I didn't belive I have accidentally removed along with some orphans or something.
Anyway, thank you and sorry not realize this before I not so good at this linux things.
-------------------------------------------------------
edit:
the package: libproxy-mozjs , installed also js60 (JavaScript interpreter and libraries).
js60 is all that my issue needed.
I installed js60 --asexplicit, and remove libproxy-mozjs.
Now I see my mistake. Can't find the date of installation of js60 in pacman, probably Yay install it, but I remove it becase it was an orphan just after the update that started my issue. Well, maybe not a mistake because js60 should be a dependency of the elogind package I guess, right now it's say that no package needs it.
---------------------
edit 2:
js60 seems an outdate package, I do have js68 installed because it's a dependency of polkit.
polkit package is who needs js, not elogind as I previously stated.
The weird thing is that is asking for the outdated js60.
